WRD overload sensing control detects and prohibits electric hoist
overloading conditions. When an overload occurs, the control prohibits
any upward travel but allows lowering of the load so that the overload
condition can be corrected. The user programmable control features
LCD displayed prompts for establishing actual hoist capacities, desired
over- load limits, and shutdown delay times (i.e. 0.1 sec.).The WRD
overload control has the ability to record the number of hours of
actual hoist operation, and the number of overload conditions that
occurred.As a service and repair feature the control records diagnostic
information that can be outputted at a later date by means of a RS-232
communications interface.
